Want a Coarse focus knob for Sky-Watcher 8" Quattro imaging newtonian

Hello all,

I've recently taken off my auto-foucuser and seemed to misplace my focus knob on my Skywatcher newtonian not the fine focus knob but the coarse knob. I've emailed skywatcherusa but no telling how long it will take. If you have one that's exact please let me know and i will be interested to buy.  But before payment is made i would like to see pictures of it first.

Best,

Darien
